- the controller 500 may be configured to decrease the output intensity of the left speaker 600 L as the passenger's ear is closer to the left speaker 600 L, and increase the output intensity of the left speaker 600 L as the passenger's ear is farther from the left speaker 600 L.
- the controller 500 may be configured to determine the output intensity of the left speaker 600 L in proportion to the distance between the passenger's ear and the left speaker 600 L. For example, the smaller the distance between the left speaker 600 L and the passenger's ear, the more the output intensity may be reduced. The greater the distance between the left speaker 600 L and the passenger's ear, the greater the output intensity.
- the controller 500 may be configured to decrease the output intensity of the right speaker 600 R as the passenger's ear is closer to the right speaker 600 R, and increase the output intensity of the right speaker 600 R as the passenger's ear is farther from the right speaker 600 R.
- the controller 500 may be configured to determine the output intensity of the right speaker 600 R in proportion to the distance between the passenger's ear and the right speaker 600 R. For example, the smaller the distance between the right speaker 600 R and the passenger's ear, the more the output intensity may be reduced. The greater the distance between the right speaker 600 R and the passenger's ear, the greater the output intensity.
- the distance d 1 between the passenger's right ear and the right speaker 600 R is less than the distance d 2 between the passenger's left ear and the left speaker 600 L.
- the controller 500 may be configured to decrease the output intensity of the right speaker 600 R and increase the output intensity of the left speaker 600 L.
- the controller 500 may be configured to calibrate the position of the passenger's ear based on the horizontal vibration among the vibrations detected by the vibration sensor 200 ( 2200 ). Specifically, if the direction of vibration detected by the vibration sensor 200 is the left direction, the controller 500 may be configured to calibrate the position of the passenger's ear in the left direction. If the direction of vibration detected by the vibration sensor 200 is in the right direction, the position of the passenger's ear may be calibrated in the right direction.
- the controller 500 may be configured to determine a calibration amount of the position of the passenger's ear in proportion to the intensity of vibration detected by the vibration sensor 200 .
- the position of the passenger's ear may be calibrated such that the distance between the right speaker 600 R and the passenger's right ear is equal to the distance between the left speaker 600 L and the passenger's left ear.
- the controller 500 may be configured to adjust the output intensity of the headrest speaker 600 based on the calibrated position of the passenger's ear ( 2300 ).
- the controller 500 may be configured to sense the state of the passenger's eyes based on the image of the passenger, and turn off the output of the headrest speaker 600 when the passenger's eyes are closed for a predetermined period of time. As shown in FIG. 9 , the eyes of the passengers are closed, and if the passenger's eyes are closed for a certain period of time, since there is a high probability that the passenger is asleep, the controller 500 may be configured to protect the passenger's hearing by turning off the output of the headrest speaker 600 .

- the control method of the vehicle 1 shown in FIG. 4 and the control method of the vehicle 1 shown in FIG. 7 are not mutually exclusive, and the output of the headrest speaker 600 according to the exact position and state of the passenger's ears may be used interchangeably to adjust the intensity.
- the controller 500 may be configured to more accurately determine the position of the passenger's ear based on information obtained from both the pressure sensor 100 , the camera 400 , and the vibration sensor 200 . For example, even if the position of the action point of the force measured by the pressure sensor 100 is biased to one side, based on the image of the passenger obtained from the camera 400 , if the position of the passenger's ear has not changed significantly, the output of the headrest speaker 600 may be adjusted based on the image of the passenger obtained from the camera 400 .
- the headrest speaker 600 may not be turned off.
- the disclosed exemplary embodiments may be implemented in a form of a recording medium for storing instructions executable by a computer. Instructions may be stored in a form of program code and, when executed by a processor, may generate a program module to perform the operations of the disclosed exemplary embodiments.
